1. A method performed by a first user equipment (UE), comprising:
transmitting, in response to a code block group (CBG)-based transmission being enabled, the CBG-based transmission on a sidelink (SL) to a second UE, wherein the CBG-based transmission comprises one or more CBGs;
receiving, from the second UE, hybrid automatic repeat request-acknowledge (HARQ-ACK) feedback corresponding to the one or more CBGs;
selecting, from one or more values corresponding to one or more pre-defined ratios, an indicator to request a resource for a CBG-based retransmission; and
transmitting, in response to the HARQ-ACK feedback, the indicator on a physical uplink control channel (PUCCH) resource.
